The following plots show the trend of weekly NPS based on the 8 variables of interest: New vs. Tenure (0-6 months vs > 6 mo.), DOP migrated vs Not, BYOD vs Buy, Autopay, OS Apple vs. Android, Sales Channel (E-Commerce, Indirect or National Retail), Single vs. Multiline, and MRC Amount (in $10 buckets). I also included additional slices worth looking into, like plan type, network provider (AT&T vs T-Mobile), and port status The first set of 8 plots display the all time survey data, and the later set just focuses on the latest 6-week period.
